Great job! I really like the form of your character! The issue I noticed in the image specs, though, is that many of the colors in your palette are so dark, that they are almost indistinguishable from the background. I thought that 19 colors looked like a lot for what is visible. Lightening the palette just slightly could make the character pop, while still masking him as if he's standing/emerging from the shadows. Either that or you could eliminate the darkest I cool colors completely. I hope you do more of these character pieces. Keep up the great work!
